DEVICE FOR SETTING INVISIBLE EYELETS.

Refiled for abandoned application Serial No. 394,090. filed July 6,1920, and in Canada June 10, 1924. This application filed June 2, 1925.Serial No. 34,361.

My invention relates to devices for setting blind or invisible eyeletsand more particularly to that class of such devices having a restrictedsetting shoulder adapted to pass 6 through a punched hole in the outerlayer of a plurality of layers and clench an eyelet upon the inner layeror layers.

The devices generally in use now'tor setting invisible eyelets belong tothe foregoing 10 class. This is particularly true of the shoemanu'lactm'ing industry in which these, dc vices have been largelydeveloped; forinvis ible evelctting has been used to a very large extentin shoes of all kinds. In the setting of invisible eyelets in shoeuppers, for instance, a holeis first punched through all the layers ofthe upper by a suitable tool, after which an eyelet is presented by alower set to the inner side ofthe upper and forced into the punched holeand against an upper set having a restricted setting shoulder. As theeyelet pushed upwardly on the upper set by the lower set, the layers ofthe shoe upper are forced upwardly by the end of the barrel of theeyelet, and the outer layer is forced over the restricted settinshoulder and into engagement with a permanent or secondary shoulderabove. Meanwhile the scored end of the barrel of the eyelet is splitinto a plurality of tongues by the restricted setting shoulder and theseare turned over by the shoulder upon the layers of the upper whichremain below the shoulder and there clenched, so that the eyelet isclenched upon the inner layer orlaycrs of the upper in register with thehole in the outer part of the upper.

la the development of these devices in the shoe manufacturing art, itwas early discovered that the distance between the setting shoulder andthe secondary shoulder above it must be just sufficient toaccon'in'lodate the outer layer of the upper and no more norno less. Itthe space was insufficient the prongs of the eyelet were pushed throughthe outer portion (generally the leather) which made a defectivesetting; if the space was too great, other layers of the upper, inaddition to the outer layer, were forced over the setting. shoulder andthe eyelet was clenched upon the wrong layer.

This necessitated the making of sets varying in dimens on between thesetting shoulder and the secondary or permanent shoulder in order tosuit various thicknesses of leather, and required the setting tool inthe cyeletting machine to be changed from time to time to conform toVariations inthe thickness of the leather; all of which consumed timeand labor and hindered the progress of the uppers through the factory.

To obviate the foregoing difficulties the secondary shoulder above thesetting shoulder was made adjustable so that the distance between thetwo might be regulated to suit different thicknesses of outer or leatherparts. That part of the setting device between the two shoulders may beeither straight or recessed; but the latter is preferable because itseems to facilitate the flipping of the outer part over the settingshoulder during the setting of the eyelet. A. setting device of therecessed type is shown in United States Letters Patent No. 1,112,643issued to L. Muther, October 6, 1911-, and in Letters Patent No.1,110,258, issued to .me September 8, 1914, is shown the Muthcr settingdevice with an adjustable nut or secondary shoulder above the settingshoulder. By turning the nut the distance between the setting shoulderand the lower face of the nut may be varied to suit the thickness of theleather or outer layer of the upper. The use of the setting device shownand described in the latter patent referred to, requires adjustmentsfrom time to time, depending upon the variation in thickness of theleather in the shoe uppers in which the eyelets are being set, but wherethe leather runs of uniform thickness, one adjustment is sufiicient.

In some cases, however, it has been found that the leather used for shoeuppers is not uniform in thickness and varies in the same upper showinga gradual increase or decrcase in thickness from the lower edgeof theupper to the top edge along the eyelet row. To secure the best resultson such upljiers the distance between the setting shoulder and thesecondary or adjustable shoulder should be changed to correspond to thegradual variation in the thickness of the leather which, of course, isimpracticable where the nut or other adjustable member is fixed inadjusted position.

The object of my invent on is the pro eyelet setting the thickness ofthe leather or outer portion ogt theshoe upper in which the eyelet isbeing set.

A further object oi. the invention is the provision of means which isetlicient, positire and accurate in operation at all times.

Other objects of the invention will be more specifically pointed out anddescribed lnueiiia'ttcr.

My invention contemplates a blind eyelet set provided with an adjustableshoulder above the setting shoulder and movable longitudinally of thesetting member, with means engaging the upper before the eyelet isclenched, for regulating the distance between the setting shoulder andthe adjustable shoulder, and means "for locking the adjustable shoulderin its adjusted position just prior to the clenching ot' the eyelet sothat iii the leather increases or decreases in thickness, the adjustableshoulder is moved away tremor toward the setting shoulder to correspondwith said increase or decrease in thickness. In consequence, when theeyelet is being clenched, the space between the setting shoulder and theadjustable shoulder is just tqual to the thickness of the leather outerpart, whatever that may be, and the leather or outer part only ispermitted to go over the setting shoulder thereby insuring theclenchii'i'g of the eyelet at the desired point upon the lining or innerlayers in register with the hole in the outer part.

in the drawings illustrating the pretcrred (IlllJOtlllllQIlb of myinvention, Figure 1 is a side elevation of a combined punch and set ofthe term shown in the Muther patent hereinl'ietore referred to, with anadjustable shoulder constructed and operated in accm'dance with myinvention; Fig. 2 is a similar elcvation on an enlarged scale of thesame showing the punch at the completion of the operation of punching ahole through the various parts making up a shoe upper, the adjustableshoulder being in an unlocked position; Fig. 3 is a view similar to Fig.2 except that the punch has fed the upper to the setting point inposition to receive the eyelet on the lower set with the adjust-ableshoulder in a locked position; Fig, 4 is a detailed view in perspectiveof the adjustable shoulder and the member carrying the same; Fig. 5 is aview in perspective of the lever for locking the adjustable shoulder inits adjusted position just prior to the clenching oi the eyelet; Fig. 6is a view in perspective of the bracket; and Figs. 7 to 12 inclusive areviews showing the various stages in the operation of setting eta blindeyelet in a shoe upper.

In the drawings I have shown my invention applied to a blind eyeletsetting device of the Muther type and as adapted particularly for use inan eyeletting machine made in accordance with United States LettcrsPatent No. 636,035, issued to Perley R. Glass, October 31 1899', but itis to hennderstood that my invention is not to be limited to theapplication herein shown and described but may be applied to blindeyelet setting devices of various other constructions adapted for use inother eyeletting machines, some of which, possibly, may require slightchanges which would, however, be apparent to one skilled in the art.

Referring to the drawings, 15 designates a punch bar furnished with athreaded bore in; its lower end to receive a blind eyelet setting deviceof the Muther type, having a threaded shank 16 adapted to be insertedwithin the threaded bore of the punch bar and a flange shoulder 17adapted to engage the end of the punch bar. The device has a centrallongitudinal bore 18 and end 19 is formed for punching a round hole. Thesurface of the device expand-s upwardly to form a restricted settingshoulder 2-0 above which a contracted portion or recess 21; and abovethat the device is straight to the flange 17. The device, because one ofits functions is to punch the hole in which the eyelet is set, iscommonly termed a punch. although it has two functions, one of punchingthe hole and the other of acting in conjunction with a lower set 22, forclenching the eyelet. Substantially all of the foregoing is old andconstitutes no part of my invention.

The novel features of my invention reside in the adjustable shoulder onthe punch for detern'iining the distance between the setting shoulderand the lower fa ot the adjustable shoulder, in the means .vhereby theposition ofthe adjustable shoulder above the setting shoulder isdetermined by the thickness of the leather at or near the point wherethe eyelet is to be set and in the means for locking the shoulder inposition atttr it has been adjusted and helore the eyelet is clenched.

in the embodiment of my invention shown in the drawings, I provide anadjustable shoulder in the term of 'a ring 30 having a central circularaperture 31 to receive the body of the punch and the ring 80 is securedto or made integral with a carrier block 33 in olliset relation thereto.The carrier block is provided with an upwardly extending spindle 36which passes loosely through a block 37 which is partially inset at 38in the punch bar and secured thereto by any suitable means. On thespin-- dle 36 between the carrier block 3 and ti e block 37 may bemounted a helical spring 40' for maintaining the carrier block, andtherefore the adjustable shoulder 30, in a loo 1 its ill lowermostposition at all times. The spindle 3b is locked within the block 37 bythe following means. A spring 41 is secured to the outer face of theblock 37 by a screw 42 and in the end of the spring mounted a long stud43 which passes through the block 37 and enters a longitudinal. recess44 cut in the spindle 36. The spindle is thereby locked against removalfrom the block 37 but has a free longitudinal movemeut equal to thelength of the recess lrl. To remove the spindle 36 from the block 37 thespring 41 is pressed to the right (referring to the drawings. Figs. 1-3)there by withdrawing the end of the stud 43 from the recess 44.

For regulating the elevation of the ad justable shoulder 30 above thesetting shoulder I provide means adapted to engage the material. inwhich the eyelet is being set, said means being adjustable to secure aproper position of the adjustable shoulder during the setting of theeyelet. Various means mounted in the carrier and adapted to engage thematerial being operated upon may be provided and one such means is shownin the drawings comprising a screw gauge 45 threaded vertically throughthe block 33 and having a round head 46 adapted to engage the material.By turning the screw gauge in one direction or the other the carrier isadjusted in vertical position with relation to the material and therebythe adjustable shoulder 30 is moved nearer to or further away from thesetting shoulder. As will be apparent. this adjustment is accomplishedwhen the punch descends to punch the hole for the eyelet in thematerial, and this operation will be explained in detail hereinafter.

After the adjustment has been made at the punching point, it is. ofcourse, necessary that the adjustable shoulder should be locked in itsadjusted position before the eyelet is set in order to prevent any butthe outer layer being pushed over the setting shoulder by the advancingeyelet. Various forms of means for locking the carrier in its adjustedposition ma be provided and one form comprises the ollowing means: Theblock 37 provided with a central transverse bore 49 which intersects thevertical bore in which is mounted the spindle 36 and in the bore 49 isinserted a cylindrical lock 50 having cut away portions 51 on oppositesides thereof and a hole 52 theretln'ough. When the lock 50 is inposition within the bore 49 the spindle 36 passes through the hole 52which is slightly larger than the outside diameter of the spindle. Ifthe lock be turned, however, the portions 53 of the lock bind againstand grip the spindle thereby locking it against longitudinal movement.For operating the lock a suitable lever 55 may be provided which mayeither be attached to the lock or made an integral part of it, and foroperating the lever I utilize one of the movements of the eyelettingmachine. y

In the machine of the Glass patent hercinbefore referred to, the punchis carried on a movable head which, after the material is punched, moveslaterally to the setting point, the punch remaining in the material andcarrying it with it. This movement I utilize in the following manner foro ')er:1ting the locking lever 55. The upper end of the lever 55 has ahole 56 adapted to receive the hooked end of a rod 58, the other end ofwhich passes loosely through a bracket fastened to a fixed part 59 ofthe frame oi the machine by a screw 61. The bracket 60 has alongitudinal slot 62 through which passes the screw 61 and this slotpermits the bracket 60 to be adjusted along said rod The rod at its freeend is provided with a head 64 and on the rod between the head 64 andthe bracket 60 is loosely mounted a helical spring (55 which is notunder compression when the punch is at the punching point. As soon,however, as the punch bar moves from the punching point to the settingpoint; that is, from right to left referring to the drawings, the rod 58is carried in the same direction, thereby compressing the spring 65which compression results in throwing the locking lever 55 to the rightand locking the spindle 36 within the blocic 37 and the adjustableshoulder 30 in its adjusted position. By varying the fixed position ofthe bracket 60 the point at which the locking takes place can be variedto some extent between the punching and the setting positions with thisqualification, that the adjustable shoulder must be free to move at thepunching point and must be locked at the setting point.

In order to disassemble the rod 58 from the bracket 60 when desired, theformer may be flattened at 67 and the latter may be provided with anopen slot 68 sutliciently wide to accon'imodate the flattened portion 67but not the rounded portion oi. the rod To separate the rod from thebracket, the former is moved in the hole (59 in the bracket until theflattened portion 67 registers with the slot 68 when that portion may bemoved out of the slot and the separation RCCOITIPliShGCl.

In operation, my device works as follows. In Figs. 7 to 12 inclusive ofthe drawings I have shown various stages in the operation of punching ahole and setting a blind eyelet therein from the initial position of themachine to the completion oil? the setting op eration. In these figures22 designates the lower set, 70 a spindle centrally disposed therein andretractable, being held in an upward position by a light spring, notshown, 71 an eyelet on the lower set con tralized by the spindle and 72a work-plate. lhe lower set and spindle, together with the \vorloplate,punch ha and general form of the llluther punch herein shown are a l oldand well known, both in construction and operation. The parts operate inthe same manner with the exception of the operation of my adjustableshoulder and itsattendant mecoanism.

in Fig. 7 is shown the initial position of the various parts before themachine is started. Upon the work-plate is laid the material which isshown as oeing made up of three layers, an outer layer 73, anintermediate layer 74- and a lower layer 75.. suming the material to bean ordinary shot upper, the outer layer 73 would be the leather or outerpart of the shoe upper, he intermediate layer 74. would be the liningand the lower layer 75 would be the facing. Sometimes additional layersare used, but as a rule the shoe upper is made up of three layers. theleather generally being much thicker than either the lining or thefacing. in this view (Fig. 7), the punch is shown in a raised positionabove the material. with the adjustable shmilder held in a downwardposition near the setting shoulder 20 by the spring 40. The lower set 22and spindle 70 are in a lowermost position underneath the opening 80 inthe work-plate and in position to receive an eyelet from the raceway.

llpon be starting of the machine, the punch bar 15 descends into theposition shown in Fig. 8, the punch punching a round hole through allthe layer of the upper. its the punch descends the round head if of thescrew guage l comes in contact with the leather 73 stopping furtherdownward movement of the carrier 33 and causing the adjustable shoulderto remain still while the punch continues its downward movement until itengages the work-plate 72. After punching the hole, the punch bar thenreleases slightly to disengage the end of the punch from the work-plateand the punch bar is fed from right to left toward the opening 80 in thework-plate; the end of the punch remaining in the hole and carrying theshoe upper with it into the posi ion shown in the next figure.

In Fig. 9, the punch has reached the setting position directly over theopening 80, the punch still remaining in the hole in the upper with thehead of the screw gauge l5 in engagement with the upper surface of theleather or outer part. During the movement of the punch from theposition shown in Fig. 8 to the position shown in llig. 9, the carrierand adjustable shoulder have been locked in position through the mediumof the rod 58 and spring 65, and the point at which the locking occursmay, of course, be regulated by adjusting the bracket 60. During themovements of the punch, as illusevant? trated in Figs. 8 and 9, thelower set 22 has taken an eyelet 71 from the raceway (not shown) and hasgradually moved upwardly into the position shown in Fig. 9.

After the punch has reached the setting point, the lower set continuesto rise and as the spindle 70 engages the lower end of the punch and thelower set continues to rise, the yelet is forced upwardly and the endo't its barrel enters between the punch and the ma terial and thenencountering the enlarged surface of the punch, the end of the barrel ofthe eyelet is broken along scored lines into a plurality of prongs. Asthe eyelet conti nues on its upward movement these prongs tend to pushthe material of the shoe upper upwardly over the setting shoulder untilthe upper face of the leat-hen or outer part engages the lower surfaceof the adjustable shoulder 30. The space between the ting shoulder andthe lower face of theiuljustable shoulder being just su'liicicnt toaccommodate the leather part 73, the lini-i'ig 7d and facing E5 of theupper remain below the setting shoulderand the prongs of the eyelet arethen turned over by the setting shoulder upon the lining and thereclenched.

in Fig. 10 the ariou parts are illustrated in the position attainedwhenv the clenching of the eyelet is halfcompleted. The setting shoulderis so formed that it turns the prongs of the eyelet over in a curvesimilar to the curve of a breaking wave so that the ends of the prongscurve downwardly, as shown in the figure, and this movement eontinuesuntil the lower set has reached the end of its upward movement and theclenching of the eyelet has been completed.

in Fig. 11 the parts are shown in their various positions atthecompletion of the setting operation, the eyelet having been clenchedupon the lining part while the outer or leather part was out of the way,above the setting shoulder. From this point the lower set descends toits initial position and the punch bar rises, withdrawing the punch fromthe material and then returns to its initial position preparatory for arepetition of the operation. In its return to its initial position thetension of the locking lever 55, due to the spring 65, is released, andwhenithe punch bar has reached its initial position, the carrier block33 is unlocked.

Fig. 12 is a view of the completed work showing the blind eyeletclenched upon the lining in register with the hole in the leather part.

As a general rule, in shoe uppers the thickness of the lining and facingcombined is uniform so that after the screw gauge has been adjusted nofurther adjustment is necessary and thereafter the adjustable shoulderis automatically adjusted by the material itself. It is immaterial,therefore,

all)

whether the thickness of the leather or outer part increases graduallyor suddenly; the adjustable shoulder takes care of the variation inthickness in any event. After the machine has been adjusted in any onefactory, any further adjustments are generally unnecessary for a verylong time, and the time now consumed in making various adjustments in anattempt to suit various thicknesses of leather is eliminated. Be causemy device takes care of gradual variations in thickness in the sameupper, which graduation it is impossible to take care of in the devicesnow in use, uniform and perfect setting of the eyelets can be secured atall times.
